SAN LUIS OBISPO — Cal Poly chemistry Professor Shanju Zhang received a $300,000 grant from the National Science Foundation to use nanotechnology to improve desalination techniques by using far less energy than traditional methods.
Currently, water is desalinated by pushing it through an osmosis membrane, which requires a great deal of pressure and, therefore, a lot of energy. With California’s ongoing drought, this new technology could provide long-term relief for the Golden State and beyond. Although a strong El Nino is expected to bring much-needed rainfall to the state this year, experts predict it might not be enough to erase four record dry-years.
Zhang and a group of students are experimenting with integrating a layer of carbon nanotubes into a desalination membrane, which would change the way the water flows.
Because water flows through nanotubes much faster than it flows outside of them — up to a million times faster — the speed of the water moving through the tubes provides the necessary pressure. Large molecules, such as salt, are too big to fit into the tubes and so will not pass through the membrane.
“These new materials will reduce the cost of water purification and improve efficiency,” Zhang said.
The key to making the nanotubes filter water is to align them vertically. To achieve this, Zhang and his students have developed a liquid crystalline polymer that holds the nanotubes and serves as the desalination membrane. Through an interdisciplinary collaboration with Xiaoying Rong, a faculty member in Cal Poly’s Graphic Communication Department, the team then prints the liquid crystal onto a substrate, similar to the way ink is printed onto paper. Because of the printing method and the qualities of the polymer, the nanotubes align.
Zhang’s students have been involved in the real-world research project from day one. “Students make the materials, use advanced instruments, and print the film. They learn a lot of lab and problem-solving skills they can't learn from a textbook. Those are real skills for the future,” Zhang said.
“My research with Dr. Zhang gives me the freedom to approach problems without following a lab manual,” said Evan Scherzinger, who presented the research team’s findings at the Western Coatings Symposium in Las Vegas in fall 2015. “This ability makes me a much better chemist and prepares me for the challenges I'll face in industry.”

Oct 14, 2015
Forget the corn mazes. Pass on the pumpkin patch. Skip the haunted house. Instead, head to Centennial Lawn on Friday, Oct. 30 for the annual Bring Your Own Pumpkin event.
Cal Poly’s chapter of the coed chemistry fraternity Alpha Chi Sigma hosts the two-hour event, which begins at 5 p.m. between Buildings 180 and 52.
As the name suggests, participants are asked to bring a pumpkin to the event. Participants then carve the pumpkins and then watch as they are blown up in one of several chemistry demonstrations scheduled to take place.
There will also be a prize drawing, a pumpkin carving contest, a costume contest, and more.

Cal Poly honored two professors from the College of Science & Mathematics with the Distinguished Scholarship Award for 2014-15: Lars Tomanek in the Biological Sciences Department and Philip Costanzo in the Chemistry & Biochemistry Department. Wyatt Brown in the Horticulture & Crop Science Department also received the award.
Costanzo conducts wide-ranging research in the emerging field of polymers and nanomaterials. One of his major areas of focus is developing materials whose properties change when the configuration of the material's atoms changes. Various triggers, such as light or temperature, can cause a change in atomic configuration, which could, for example, erase scratches in paint.
All of Costanzo's numerous publications at Cal Poly have included student co-authors, many of whom have gone on to doctoral programs at top-tier universities. He has received more than $1 million in grant funding since his arrival in 2007.
"Phil shows what's possible with undergraduate researchers. He provides them a significant experience doing relevant, applied research in polymer chemistry," said Nanine Van Draanen, chair of the Chemistry & Biochemistry Department.
Tomanek's research focuses on how marine organisms respond to climate change. Using a cutting-edge technique called environmental proteomics, Tomanek and his students analyze how environmental stresses affect protein production, which can predict an organism's reaction to climate change.
Since coming to Cal Poly in 2005, Tomanek has been awarded $2.4 million in grant funding, much of it from the National Science Foundation (NSF). Many of Tomanek's 23 peer-reviewed papers include his undergraduate and graduate students as co-authors, and his students have led NSF-funded workshops for faculty from other universities. Tomanek is also a co-leader of the Environmental Effects on Coastal Organisms network of CSU researchers.
"Lars' work not only provided opportunities for other biology faculty to branch out into new directions using his proteomics approach but also gave our students the opportunity to do work more often performed by doctoral students and postdoctoral researchers at other universities," said Chris Kitts, chair of the Biological Sciences Department.
The Distinguished Scholarship Award was established in 2003 to recognize faculty achievements in research, creative work and other professional development activities. The award supports research and other creative endeavors and encourages the professional growth of Cal Poly faculty members.

Cal Poly's chapter of the co-ed chemistry fraternity Alpha Chi Sigma was honored with the T. Dale Stewart award for best chapter nationwide for 2012-14. Given every two years, the award is based on the quantity and quality of events the chapter participates in and sponsors.
The students in the Cal Poly chapter host or help with a variety of events on campus and in the community. They provide free chemistry tutoring services on campus, help Boy Scouts earn their science merit badge, participate in community science nights, and assist local high schools with chemistry labs and experiments.
"These activities benefit the K-12 students by providing them with resources, and the Cal Poly undergraduates learn better ways to communicate science with the general community," said Phil Costanzo, a chemistry professor and the club's advisor.
The students also sponsor a campuswide BYOP (bring your own pumpkin) party every Halloween, during which they carefully carve and then blow up pumpkins.
"Alpha Chi Sigma is a great opportunity for students because it opens up a whole new community on campus," said Jennifer Dunaj, a chemistry major and the chapter's master alchemist, as the chapter leader is called. "You always see a friendly face in class and have someone to talk to."
The fraternity also facilitates networking with chemistry professionals, including faculty members and those working in industry. "Alpha Chi Sigma enables students to form connections that help open paths to research, internship and job opportunities," said Dunaj.
"The students have worked hard for this award. They're a dedicated group and really enjoy sharing their love and passion of chemistry with others," said Costanzo.
